Mn(II),Co(II) ,Ni(II),Cu(II)and Hg(II)metal complexes of Schiff base(2,2'-(1E,1'E)-(ethane-1,2-diylbis(azan-1-yl-1-ylidene))bis( phenyl methan-1-yl-1-ylidene)di benzoic acid)derived from 2-benzoylbenzoic acid and ethylene diamine have been synthesized and characterized by IR ,1H-,13C-NMR (only ligand) and electronic spectra, elemental analysis, in addition of magnetic moment measurements and molar conductance. It has been found that the Schiff base ligand behaves as tetradentate (N2O2) ligand forming chelates with 1:1 (ligand: metal) stoichiometry. The conductivity data for all complexes are consistent with those expected for non-electrolyte nature.It found that all complexes showed octahedral geometries. And in vitro tests for antibacterial and antifungal activity showed that most of the prepared compounds display a good activityto (staphylococcus aureus), (Escherichia coli), (Bacillus subtilis) and (Pseudomonas aeruginosa).
